## Plain English

The agent can use software more like a person when APIs are missing.

## Example

An agent opens a desktop app, fills a form, clicks submit, and reads the confirmation screen.

## Why it matters

Computer use expands automation to legacy apps, but it requires strong sandboxing and oversight.
